IMPROVEMENT IN APPARATUS FOR I IQUORING SUGAR IN CENTRIFUGAI. MACHINES.

Specification forming part of Letters Patent No. 221,893, dated November 18, 1879 g application lcd September 2, 1879.

lcontact for the purpose of preventing the escape of the white liquor otherwise than through the sugar contained in the molds, and from which the boxes are, by the opposite motion, withdrawn for the purpose of freeingthe molds, so that they can be moved from the machine when the liquoring operation is completed; and my inventionconsists in the combination l of the boxes with a diametrically or vertically expansible chamber lled with. a iuid and provided with a movable plunger so organized that it may be forced into the chamber for the purpose of causing the expansion of the elastic parts of the chamber, or withdrawn therefrom for the purpose of causing the retraction of the elastic parts of the chamber.

The accompanying drawings, illustrating a centrifugal machine containing my invention, are as follows: Figure l is a central vertical section of the machine, showing the boxes thrust outward against the molds by the depression of the plunger in the expansible chamber. Fig. 2 is a top view, partly in section, and Fig. 3 is a central vertical section, showing the boxes withdrawn from contact with the molds, owing to the elevation of the plunger and the reduction in the diameter of the expansible chamber.

The drawings represent the usual basket A of a centrifugal machine mounted upon a vertical spindle, B, and containing a series of concentrically-placed sugar-molds, C, seated in the usual manner between guide walls or pillars c, permanently affixed to the basket.

The machine is provided with the usual central reservoir, D, having the spouts d, by which its contents are discharged into the usual liquoring-boxes E. These boxes are closed at the back or inner side, and are, respectively, affixed to the elastic or flexible shields j, which close the openings in the periphery of the expansible chamber F. These shields may be made of rubber fabric, leather,'or any flexible material which is water-tight, and they are connected by water-tight joints with the metallic wall of the chamber F.

The range of radial movement required for the boxes is very small, and their connection, respectively, with the shields f serves to hold them in proper radial alignment with the molds.

The metallic top F of the chamber F is centrally perforated to admit the tubular plunger Gr, and is provided with a flanged packing, F2, and cap F3 for the purpose of packing the joint with the tubular plunger G. The interior of the hollow plunger Gr is provided with the female screw-thread g, which engages a male screwthread on the upper portion, g', of the spindle. The upper end of the plunger G may be provided with a crank, or may be made polygonal for the application of a wrench by which means it may be turned either` to force it down into the chamber F or withdraw it therefrom.

The chamber F is filled with water or other uid, so that when the plunger is forced down into the chamber the displacement of the contained iiuid will effect the expansion of the elastic shields and consequent thrusting of the boxes radially outward against the molds.

By the reverse movement of the plunger G the previously-displaced liuid re-enters the chamber F, and the elastic shields are drawn inward by atmospheric pressure, withdrawing the boxes from the molds, so that the latter can be removed from the basket of the machine.

I claim as my invention in centrifugal liquoring apparatusl. A series of movable boxes concentrically arranged in the basket of a centrifugal machille, in combination with an expansible ohnmber7 with the elastic portion of the side Walls of which such boxes are connected, as latnd for the purposes set forth.

2. A central chamber. in the basket of a centrifugal machine, having portions of its side Walls, with which zt series of movable boxes are connected, composed of an elastic or flexible material, in combination with a. movable plunger for efrfeoting;` the displacement of a iuid Contained Within the central chamber, as and for the purpose set forth.
